[The] gross ignorance of the mass of people, including even the so-called scientists and philosophers, makes life a risky situation in which human beings do not know whether they are making progress in life. According to Srimad-Bhagavatam (7.5.30), they are simply progressing to the darkest region of material existence. . . . The Krishna consciousness movement has therefore been started to give philosophers, scientists, and people in general the proper knowledge about the destiny of life. Everyone should take advantage of this movement and learn the real goal of life.
His Divine Grace A. C. Bhaktivedanta Swami Prabhupada
Srimad-Bhagavatam 4.21.23, Purport

That which the Vedantists describe as unmanifest and infallible, that which is known as the supreme destination, that place from which, having attained it, one never returns – that is My supreme abode.
Lord Sri Krishna
Bhagavad-gita 8.21

All sins are destroyed and all good fortune is created by the Supreme Lord’s qualities, activities, and appearances, and words that describe these three things animate, beautify, and purify the world. On the other hand, words bereft of His glories are like the decorations on a corpse.
Sri Akrura
Srimad-Bhagavatam 10.38.12

It has been conclusively decided in the scriptures, after due consideration, that the ultimate goal for the welfare of human society is detachment from the bodily concept of life and increased and steadfast attachment for the Supreme Lord, who is transcendental, beyond the modes of material nature.
Sri Sanat-kumara
Srimad-Bhagavatam 4.22.21

All glories to the Supreme Personality of Godhead, who is called by different names such as Hari, Krishna, and Rama! He is the auspicious resting place of all living entities within the universe, and He delights the minds of all souls. Wise sages maintain great reverence for His holy name and constantly sing it by filling their mouths with the sound.
Srila Bhaktivinoda Thakura
Sri Namashtaka, 2

His abundantly beautiful complexion belittles the splendor of combined rainclouds, black eye cosmetics, and sapphires. His garments appear effulgent like a rising sun tinted like kumkum powder and enhanced by shining bolts of lightning. His perfectly-formed limbs are anointed with sandalwood paste mixed with camphor and saffron. May Sri Krishna, the son of the king of the cowherd men, grant me the service of His own lotus feet.
Srila Krishnadasa Kaviraja Goswami
Govinda-lilamrita 17.51

When the universe became three fourths filled with sin, the eternal Lord Sri Krishna appeared at Navadvipa as Sri Gaurasundara [Chaitanya Mahaprabhu]. He appeared in order to deliver the wretched living entities of Kali-yuga, who were drowning in the ocean of birth and death.
